' Application filed Marchh 16, 1925. Serial No. 16 0095 ToaZZ whom itmay concern."

Be it known that I, VALTER H. SEAVEY,

a citizen of' the Unitedls'tat'es, residing at Kearsarge, in tliecountyof Garroll and- State of New Hampshire, have invented new and'usefulImprovements in Saw 2 of which the following is a specification.

This invention relates to saw rigs and has for an objectthe provision ofa rig which is simple inconstruction, easy to op-' crate and may bereadily transported from place to place, the invention being especiallyadapted fbr sawing cord wood.

Another object of the invention is the provision ofnovel means forfeeding the wood'to the saw, whereby'operation of the latter will exerta'downward pressure uponthe' wood and greatly facilitatethe operationof"sawing,-so that a given amountof material may be sawedi'n' arelatively short time and with a-mi'nimum'amount of labor.

Another. object of] the invention is the provision of novel" means foradjusting the level of the feeding table so that the latter may beproperly adjusted for use even though the rig is out of level.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure 1 is a side elevation of a saw rig constructed inaccordance with the invention.

Figure 2 is a'front view of the same.

Figure 3 is a top plan view.

Figure 4 is a longitudinal sectional view.

Referring in detail to the drawings wherein like characters of referencedenote corresponding parts, the rig is shown as comprising a supportingframe, the latter including spaced sills or runners 10 from which risestandards 11. These standards are connected by longitudinal timbers 12and transverse connecting bars 13. A rigid frame is thus provided whichmay be supported in any manner such as wheels or runners, the sills 10serving as the latter. If desired the frame may be supported upon abench or table, according to the character of the work for which it isintended.

Mounted in bearings 14 supportedupon the sills 10 is a shaft 15 andsecured upon this I shaft is-asaw blade 17 Also secured upon the shaft15 is apulley 18 which is-driven .by a belt 19-an'dth'e lattermay'befoperated fromany suitable source of. power such as a motororjengine, 'either mounted-Rupert the supportingfranie or mountedseparately therefrom. The belt is preferably pro vided with an automatictightener shown in the form ofa= roller. 20 whichengages the belt, andwhich is carried at oneend of an arm21-=,:the opposite endz. of which ispivot.-

ally mounted upon the frame asshown, at

Supported by the frame just describe'd' is: a feeding frame, the latter"inclilding spaced' parallel substantiallyhorizontallydisposed"- beams 23to thenfrontiends-off whichis s.ecured atable 24 uponwhich the inateria'lzis placed to be fed to thesaw'; This tableiis transverselyslitted' as shown at 25 to. receive; the saw and i carries a" guard: 26'forfthe: protect'io'n of tlieoperator Bivot'ally secured adi ac-ent the:front ends-of. thesbeams 23; are the lower ends of hanger bars 27 Theupper ends of these bars are pivotally secured to the timbers 12throughthe medium of a rod 28, the outer ends of which extend throughslots; 29 provided in the timbers 12. The point of connection betweenthe hanger bar 27 andthe timbers 12 may thus be regulated by moving therod 28 in the slots 29. The rear ends of the beams 23 have pivotallysecured thereto the lower ends of rear hanger bars 30, the upper ends ofwhich are pivotally secured to the timbers 12 as shown at 31. The pointsof connection of the upper ends of the bar 30 are in advance of thepoints of connection of the lower ends of these bars so that thetendency of the feeding frame just described will be to move the table24 away from the saw blade 17.

The position of the table 24 with relation to the blade 17 is such thatwhen work upon the table is fed toward the saw the latter will engagethe work in such position as to exert a downward pressure so that therewill be no tendency of thework to raise from the table. The-operation ofsawing will thus be materially assisted.

Mounted in bearings 32 provided in the bars 13 is a longitudinallydisposed threaded rod 33. Mounted upon and threadedly engaging this rodis a nut 34. Rods 35 have one of their ends secured to the nut 34 whilethe opposite ends of these rods are secured to the front hanger bars 27as indicated at 36, so that by rotating the threaded rod '33 the nutwill be moved longitudinally of the rod and will carry with it the upperends of the hanger bars 27 so as to regulate the pivotal positions ofthese rods. The threaded rod 33 is preferably provided with an operatinghandle 37.

By changing the pivotal points of the upper end of the hanger bars 27the position of the table 24 may be regulated so that the e said tablemay be leveled even though the supporting frame is out of level.

The invention 1s susceptible of various changes 1n 1ts form, proportionsand minor details of construction and the right is here-.

in reserved to make such changes as properly fall within the scope ofthe appended claims.

Having described the invention what is claimed is g I I 1. A. saw rigcomprising a supporting frame, a saw blade mounted for rotation thereon,means whereby the blade may be driven, a feeding frame comprising spacedsubstantially horizontally disposed beams, a feeding tablesecured to thefront ends of the beams and normally spaced from the saw, front hangerbars having their lower ends pivotally secured to the beams and theirupper ends pivotally supported in the supporting frame, rear hanger barshaving their lower ends pivotally secured to the lower ends of the beamsand their upper ends pivotally secured to the supporting frame inadvance of the pivotal connections of their lower ends, whereby thetable will normally swing in a direction away from the saw and means forregulating the point of connection of the front hanger bars and thesupporting frame.

2. A saw rig comprising a supporting frame, a saw blade mounted forrotation thereon, means whereby the blade may be driven, a feeding framecomprising spaced substantially horizontally disposed beams, a feedingtable secured to the front ends of the beams and normally spaced fromthe saw, front hanger bars having their lower ends pivotally secured tothe beams, a slidable pivotal connection between the upper ends of saidbars and the supporting frame, rear hanger bars having their lower endspivotally secured to the rear ends of the beams and their upper endspivotally secured to the supporting frame in. advance of the pivotalconnections of their lower ends, whereby the table will normally swingin a direction away from the saw, a threaded rod extendinglongitudinally of and mounted in bearings carried by the supportingframe, a nut mounted upon the rod and rigid means connecting the nut andfront hanger bars,
